We can't do instant reconnect, not to DDoS server, but we should stop and failover earlier, so there is less service interruption. To avoid deadlock, as error_recovery is called from different callback like rdma event or hb error handler, add a new err recovery_work.

2022-01-22lib/stackdepot: allow optional init and stack_table allocation by kvmalloc()Vlastimil Babka4-0/+17
Currently, enabling CONFIG_STACKDEPOT means its stack_table will be allocated from memblock, even if stack depot ends up not actually used. The default size of stack_table is 4MB on 32-bit, 8MB on 64-bit. This is fine for use-cases such as KASAN which is also a config option and has overhead on its own. But it's an issue for functionality that has to be actually enabled on boot (page_owner) or depends on hardware (GPU drivers) and thus the memory might be wasted. This was raised as an issue [1] when attempting to add stackdepot support for SLUB's debug object tracking functionality. It's common to build kernels with CONFIG_SLUB_DEBUG and enable slub_debug on boot only when needed, or create only specific kmem caches with debugging for testing purposes. It would thus be more efficient if stackdepot's table was allocated only when actually going to be used. This patch thus makes the allocation (and whole stack_depot_init() call) optional: - Add a CONFIG_STACKDEPOT_ALWAYS_INIT flag to keep using the current well-defined point of allocation as part of mem_init(). Make CONFIG_KASAN select this flag. - Other users have to call stack_depot_init() as part of their own init when it's determined that stack depot will actually be used. This may depend on both config and runtime conditions. Convert current users which are page_owner and several in the DRM subsystem. Same will be done for SLUB later. - Because the init might now be called after the boot-time memblock allocation has given all memory to the buddy allocator, change stack_depot_init() to allocate stack_table with kvmalloc() when memblock is no longer available. Also handle allocation failure by disabling stackdepot (could have theoretically happened even with memblock allocation previously), and don't unnecessarily align the memblock allocation to its own size anymore.

Fix this by moving page_ext_init_flatmem_late() below kmem_cache_init() so that slab_is_available() is true during stack_depot_init(). SPARSEMEM doesn't have this issue, as it doesn't do page_ext_init_flatmem_late(), but a different page_ext_init() even later in the boot process. Thanks to Mike Rapoport for pointing out the FLATMEM init ordering issue. While at it, also actually resolve a checkpatch warning in stack_depot_init() from DRM CI, which was supposed to be in the original patch already.

2022-01-22scsi/sg: move sg-big-buff sysctl to scsi/sg.cXiaoming Ni1-1/+34
kernel/sysctl.c is a kitchen sink where everyone leaves their dirty dishes, this makes it very difficult to maintain. To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic. So move the sg-big-buff sysctl from kernel/sysctl.c to drivers/scsi/sg.c and use register_sysctl() to register the sysctl interface.

2022-01-22random: move the random sysctl declarations to its own fileXiaoming Ni1-2/+12
kernel/sysctl.c is a kitchen sink where everyone leaves their dirty dishes, this makes it very difficult to maintain. To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic. So move the random sysctls to their own file and use register_sysctl_init().

2022-01-22firmware_loader: move firmware sysctl to its own filesXiaoming Ni3-3/+40
Patch series "sysctl: 3rd set of kernel/sysctl cleanups", v2. This is the third set of patches to help address cleaning the kitchen seink in kernel/sysctl.c and to move sysctls away to where they are actually implemented / used. This patch (of 8): kernel/sysctl.c is a kitchen sink where everyone leaves their dirty dishes, this makes it very difficult to maintain. To help with this maintenance let's start by moving sysctls to places where they actually belong. The proc sysctl maintainers do not want to know what sysctl knobs you wish to add for your own piece of code, we just care about the core logic. So move the firmware configuration sysctl table to the only place where it is used, and make it clear that if sysctls are disabled this is not used.

2022-01-22hpet: simplify subdirectory registration with register_sysctl()Luis Chamberlain1-21/+1
Patch series "sysctl: second set of kernel/sysctl cleanups", v2. This is the 2nd set of kernel/sysctl.c cleanups. The diff stat should reflect how this is a much better way to deal with theses. Fortunately coccinelle can be used to ensure correctness for most of these and/or future merge conflicts. Note that since this is part of a larger effort to cleanup kernel/sysctl.c I think we have no other option but to go with merging these patches in either Andrew's tree or keep them staged in a separate tree and send a merge request later. Otherwise kernel/sysctl.c will end up becoming a sore spot for the next merge window. This patch (of 8): There is no need to user boiler plate code to specify a set of base directories we're going to stuff sysctls under.

2022-01-21HID: wacom: Avoid using stale array indicies to read contact countJason Gerecke1-0/+4
If we ever see a touch report with contact count data we initialize several variables used to read the contact count in the pre-report phase. These variables are never reset if we process a report which doesn't contain a contact count, however. This can cause the pre- report function to trigger a read of arbitrary memory (e.g. NULL if we're lucky) and potentially crash the driver. This commit restores resetting of the variables back to default "none" values that were used prior to the commit mentioned below.

2022-01-21HID: wacom: Ignore the confidence flag when a touch is removedJason Gerecke1-3/+26
AES hardware may internally re-classify a contact that it thought was intentional as a palm. Intentional contacts are reported as "down" with the confidence bit set. When this re-classification occurs, however, the state transitions to "up" with the confidence bit cleared. This kind of transition appears to be legal according to Microsoft docs, but we do not handle it correctly. Because the confidence bit is clear, we don't call `wacom_wac_finger_slot` and update userspace. This causes hung touches that confuse userspace and interfere with pen arbitration. This commit adds a special case to ignore the confidence flag if a contact is reported as removed. This ensures we do not leave a hung touch if one of these re-classification events occured. Ideally we'd have some way to also let userspace know that the touch has been re-classified as a palm and needs to be canceled, but that's not possible right now :) Link: https://github.com/linuxwacom/input-wacom/issues/288 Fixes: 7fb0413baa7f (HID: wacom: Use "Confidence" flag to prevent reporting invalid contacts) CC: stable@vger.kernel.org Signed-off-by: Jason Gerecke <jason.gerecke@wacom.com> Reviewed-by: Ping Cheng <ping.cheng@wacom.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
2022-01-21HID: wacom: Reset expected and received contact counts at the same timeJason Gerecke1-1/+5
These two values go hand-in-hand and must be valid for the driver to behave correctly. We are currently lazy about updating the values and rely on the "expected" code flow to take care of making sure they're valid at the point they're needed. The "expected" flow changed somewhat with commit f8b6a74719b5 ("HID: wacom: generic: Support multiple tools per report"), however. This led to problems with the DTH-2452 due (in part) to *all* contacts being fully processed -- even those past the expected contact count. Specifically, the received count gets reset to 0 once all expected fingers are processed, but not the expected count. The rest of the contacts in the report are then *also* processed since now the driver thinks we've only processed 0 of N expected contacts. Later commits such as 7fb0413baa7f (HID: wacom: Use "Confidence" flag to prevent reporting invalid contacts) worked around the DTH-2452 issue by skipping the invalid contacts at the end of the report, but this is not a complete fix. The confidence flag cannot be relied on when a contact is removed (see the following patch), and dealing with that condition re-introduces the DTH-2452 issue unless we also address this contact count laziness. By resetting expected and received counts at the same time we ensure the driver understands that there are 0 more contacts expected in the report. Similarly, we also make sure to reset the received count if for some reason we're out of sync in the pre-report phase.

Commit 0f153a1b8193 ("usb: chipidea: Set the DT node on the child device") caused the child device to match on the parent driver instead of the child's driver since the child's DT node pointer matched. The worst case result is a loop of the parent driver probing another instance and creating yet another child device eventually exhausting the stack. If the child driver happens to match first, then everything works fine. A device sharing the DT node should never do DT based driver matching, so let's simply check of_node_reused in of_match_device() to prevent that.
